Window sash stop



March 27, 1962 H. K. LUNDGREN WINDOW SASH STOP Filed Feb. 25, 19603,026,580 WINDOW SASI-I STGP Herbert K. Lundgren, Oshkosh, Wis.,assignor to Allmetal Weather-strip Company, a corporation of IllinoisFiled Feb. 26, 1960, Ser. No. 11,283 6 Claims. (Cl. 2li-52) Thisinvention is directed generally to window constructions and particularlyto an improved installation carrying slidable, double hung windowsashes. More especially, the invention is directed to novel means whichprovide the duel function of securing a sash guide and weather strippingelement within a window frame and of limiting sliding movement of thesashes within their mounting frame.

Accordingly, the principal object of the invention is the provision of anew and improved window sash mounting construction. A further object ofthe invention is to provide a window sash stop and fastener elementwhich provides for easier and more economical installation of the sashguide structure while, at the same time, providing a sash travel limitfeature which prevents marring or damaging of the installation duringuse.

' Other objects and advantages of the invention will become apparent byreference .to the following description and accompanying drawings inwhich:

FIGURE 1 is a sectional view of a window installation incorporating thefeatures of this invention;

FIGURE 2 is a fragmentary sectional view taken along line Z-Z of FIGURE1;

FIGURE 3 is a fragmentary front View, partially broken away,illustrating a lower corner of the window mounting construction shown inFIGURE 1;

FIGURE 4 is an enlarged, fragmentary, partially broken away, view takenalong line 4 4 of FIGURE l;

FIGURE 5 is an enlarged, fragmentary, partially broken away, sectionalView taken along line 5 5 of FIGURE l; and

FIGURE 6 is an enlarged, perspective view of the novel stop-fastenerelement employed in the disclosed construction.

The window construction illustrated in the drawings incorporates the useof a novel element 11, which serves as a fastener and as a stop means soas to secure a combination sash guide and weather stripping element 13within a window frame 15 and to limit travel of a pair of sashes 17carried by the window frame.

The particular wooden window frame 15 shown in FIGURES l and 2 istypical of many constructions and incorporates an upright end member 19extending between upper and lower transverse frame members 21 and 23. Ofcourse, it should be understood that although the description concerns avertically double hung installation, the advantages of the invention arereadily realizable in a horizontally double hung installation.

`Fastened by a pair of the stop-fasteners 11 in overlying relation 4tothe upright end member 19 is the combination sash guide and weatherstripping element 13 which provides guide tracks for each of the pairsof window sashes 1'7. Except as otherwise indicated, the combinationsash guide and weather stripping element 13 can be of any knownconstruction. In the disclosed construction, the sash guide 13 includesa central parting stop of U-shaped formation and a pair of springhousings 27 which extend into mating vertical side recesses 29 in thewindow sashes 17, thereby also providing guidance for the travelthereof. Each of the window sashes 17 carries one of a pair ofengageable lock members 31 and 33, the lock member 31 commonly carriedon the lower sash being movable into the path of movement of thePatented Mar. 27, 1962 upper sash for locking interconnection with themember 33.

Considering the constructional features of the stopfastener element 11,which facilitates its dual employment to serve the purposes explained,the element 11 is formed of a strip of metal, such as steel, andincludes a U-shaped end portion 35 which is slidably engageable over theend edges 37 of the combination sash guide and weather stripping element13, and incorporates a spring clip feature to prevent accidentaldisconnection of the component 11 from the element 13 prior toinstallation in the frame 15, and to secure the stop-fastener relativeto the sash guide 13. The other end of the stop-fastenerextends in theopposite direction from the open end of the U-shaped portion 35 and inpartially adjacent, offset parallel relation thereto. This end 39includes a pointed outer extremity 41 extending beyond the U-shapedportion 35 for impalement in one of the wooden transverse members 21 and23. Connecting the pointed end part 39 and the U-shaped end portion 35is a bent segment 43 having one leg 45 disposed generally perpendicularto the general disposition of the pointed end part 39 and U-shaped endportion 35 for location, in the finished installation, transverselyacross the path of sash movement to limit the travel of the sash in itsguide track, and thereby prevent contact between the sash and theadjacent frame member. More particularly, the segment 43 is preferablyrectangular in configuration, with the leg 44 disposed parallel to theleg 45 and joined therewith by a section 46 at right angles to the twolegs. Although other shapes might be employed for the segment 43, thedescribed arrangement is especially designed to withstand the forcesordinarily directed against the stop-fastener during its installationand use.

As most installations commonly utilize a sash guide and weatherstripping element 13 extending the full height of the window frame, someprovision should be incorporated for permitting engagement of thestopfastener 11 with the sash guide 13 to facilitate initial assemblytherebetween, so that the pointed extremity 41 of the component does notinitially extend beyond the end edges 37 of the sash guide and weatherstripping element and, therefore, does not interfere with the placementof the sash guide and Weather stripping element 13 against the end framemember 19. In the disclosed construction, this feature is provided bycut-outs 51 in the opposed sides and at opposite ends of the partingstop 25, which cut-outs 51 extend for at least approximately the lengthof the pointed extremity 41 which projects beyond the U-shaped portion35. Of course, the cut-outs 51 are not as long as the U-shaped portionitself.

During erection of the window mounting construction, one of thestop-fastener elements 11 is slidably engaged with the combination sashguide and weather stripping element 13 at each end on opposed sides ofthe parting stop 25 and extends within the cut-outs 51 formed therein.As pointed out previously, this engagement includes a degree ofover-travel required to prevent projection of the pointed extremity i1beyond the adjacent end edge 37 of the sash guide 13. The guide 13 isthen laid yflush against the end frame member 19, and the pointedextremities 41 of the stop-fasteners 11 are driven into the wooden topand bottom transverse members 21 and 23, respectively, thereby securingthe combination sash guide and weather stripping element in lixedrelation to the end frame member. When thus installed, the leg 45 of thebent segment 43 extend in the path of sash travel to prevent striking ofthe upper frame member 21 by the lock member 31 incident to excessiveupward movement of the lower sash. In addition, the stop-fastener at thelower end of the combination sash guide and weather stripping elementwill limit downward movement of the upper sash, so that the upper crossbar 53 thereof cannot be lowered to a position of possible damaginginterference with the lock member 3l which, when the inner sash is fullylowered, may be unintentionally located in the path of travel of theupper sash. Thus, the disclosed stop-fastener functions eifectively bothto easily secure the combination sash guide and weather strippingelement in position on the end frame member and to limit travel of thewindow sashes to preclude damage to the sashes and the mounting framestructure.

Although shown and described with respect to a particular construction,it will be apparent that various modifications might be made withoutdeparting from the principles of this invention. For example, thestop-fastener element might be of a different configuration and stillserve its intended purpose, and it might be positioned elsewhere thandescribed with respect to the sash guide i3.
